Instagram Carousel Image Size Guide (2026)

Instagram carousels can combine up to multiple slides, but each slide should be prepared with the same ratio to avoid unpredictable crop behavior. If slide one is square and slide two is portrait, the platform may force a shared framing rule based on the first asset, causing clipping on later slides.

Recommended dimensions

• Square carousel: 1080 x 1080 (1:1)
• Portrait carousel: 1080 x 1350 (4:5)
• Landscape carousel: 1080 x 566 (1.91:1)

Safe margin strategy

Even when dimensions are correct, edge-heavy designs can still feel cramped in feed previews. Keep key headlines, logos, and CTAs away from the outer margins.

• leave 60-90 px breathing room around edges for text-heavy slides
• keep branding elements in the central 70 percent of each canvas
• avoid tiny text that relies on pinch-zoom to be legible

Publishing workflow

1. Choose one ratio and apply it to every slide in the set.
2. Export all slides in the same format and quality profile.
3. Run a preview check on mobile before final publish.
4. Verify that slide transitions do not break text continuity.

Practical tip: if your message depends on sequence, include slide numbers directly in the design so readers keep orientation as they swipe.
